Is there any up-to-date list with ASNs of cloud hosting providers?

We have a user facing domain with APIs and few webpages on it. The domain is meant for interactions with users from mobile ISPs, not hosting providers.

We are using Cloudflare Enterprise and it consists of managed IP lists for Open Proxies, VPNs, etc. While Open Proxies and VPNs a manageable risk, the major risk is hosting providers. Every now and then theres an abuse of API endpoints from obscure hosting providers. After every abuse we block ASNs of the provider. This solution is not perfect as every time we block one hosting provider, the abuse happens from a different hosting provider within a week or two.

I cant find a managed list of Hosting Providers by Cloudflare. Is there a managed list elsewhere which is up-to-date with the current hosting providers.

PS: I have checked GitHub projects like https://github.com/brianhama/bad-asn-list and https://github.com/LorenzoSapora/bad-asn-list but they are not regularly updated

Maybe try ARIN - Requesting IP Addresses or ASNs - American Registry for Internet Numbers

That would be some list though, potentially 4,294,967,296 ASNs

Countries ASNs | IPInsight.io list by country then each countries ASNs and who they belong to, as does ASNs by countries - IPinfo.io

ipinfo.io also have their ASN API which would give you type
